Title: Improvements in or relating to radio and like modulated carrier wave receivers
IPC: H04B1/30
Filed: 1934-04-28
Abstract: 437,306. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and WRIGHT, G. M., Lordlands, Little Baddow, Chelmsford, Essex. April 28, 1934, No. 12902. [Class 40 (v)] In homodyne receivers of the kind in which tuning is effected by varying the frequency of the homodyne oscillator, the tendency with such arrangements for the oscillator to move out of step with the received carrier is prevented by replacing the usual fixed inductance and variable condenser in the oscillator circuit by a variable tapped inductance or variometer 3, tuning with its distributed capacity. Where a tapped inductance is used a small shunt condenser may be used for fine tuning. In the arrangement shown, the oscillator is constituted by a back-coupled homodyne detector 6.

[Class 106 (i).] Multiplying ; adding and subtracting. A record-card controlled machine for evaluating expressions of the form a x b + c, where c may be an amount or a second product, has means for reading these amounts from each of the cards, registers into which the terms are entered, multiplying mechanism for automatically obtaining the product of two terms, and accumulators into which the right and left hand components of the partial products are entered. According to the invention the multiplying mechanism is adjustable to obtain either the product of two terms or alternatively the complement of the product and the accumulator is arranged to sum the amounts obtained by the multiplying mechanism whether such amounts are true products or complements. Provision is made for the addition of the "fugitive 1." The machine is mechanically similar to that described in Specification 405,031 but the electrical circuits have been modified in accordance with the invention. The machine as shown in Figs. 1 and 2 includes a motor M for driving an A.C., D.C. generator 52, multiplicand registers MC1, MC2, multiplier registers MP1, MP2, a multiplier relay unit MPR, a column shift relay unit CS for controlling the column circuits of the sections LH, RH of the accumulator. The machine also includes a card feed unit and a punching mechanism of well known form. The registers and accumulator are provided with reading-out commutators of the type described in the above mentioned Specification. The cycle controlling mechanism is similar to that described in Specification 358,105, and a set of multi-contacts PS is employed to place the controller firstly under the control of the readout mechanism of the register MP1 and then under that of register MP2. A manually operated switch is provided to connect the multiplying circuits in reversed order to one or other of a pair of impulse emitters depending on whether the successive products are to be added or subtracted. The machine may be employed to calculate net amounts from gross amounts and discount rates. The cards will be punched with the gross amount, the discount rate, and unity, the machine being adjusted to subtract. The Specification as open to inspection under Sect. 91 comprises also a modification of the machine wherein the amount that is to be added to or subtracted from the first product is entered into an inverter register and may be read out therefrom as a true amount or as its complement. This subject-matter does not appear in the Specification as accepted.

[Class 87 (ii)] [Also in Group XV] A cricket or hockey ball is formed by coating a hard core 11 with a thin moulded cover 12 of suitable polyvinyl chloride composition. An adhesive is first applied to the core. Hemispherical cups of incompletely-cured polyvinyl chloride composition are first formed between moulds 14, 15 having heaters 18, 17 respectively. Mould 15 carries a changeable member 20 having a patterned surface to emboss the cups, the hollows in which are filled with polyvinyl chloride composition of a different colour before final moulding. The cups are formed with a cylindrical extension 19 or a peripheral rim. Two cups are then placed around an adhesivecoated core 11 which is moulded between mould parts 22 held in a sleeve 24 and having grooves 23 filled with differently-coloured P.V.C. composition to simulate " stitching." Several of the sleeves 24 are mounted in a screw press (Fig. 7, not shown) and the moulding is effected in an autoclave, an oil bath or a convection oven. In modifications, the core is covered by wrapping in sheet P.V.C. composition and then moulding, or by dipping in polyvinyl chloride paste and then moulding. Alternatively the core may be centred in a mould by blobs of P.V.C., sufficient P.V.C. to form the cover having previously been inserted. Examples are given in the Specification of a suitable composition and of suitable moulding times and temperatures.
